side of my door.

Be it known that I, JOHN FLESHER, a sue eot of the King of GreatBritain, residing at Parry Sound, in the district of ParrySound andProvince of Ontario, Canada, have in Vented a new and useful Door forGrain-Cars,

of which the following is aspecificationa Y My invention relates toimprovements in doors for grain-cars or: other receptacles for :0

grain and like products and the object of my invention is to design adoor which may beeasily opened or closed,whieh may be hung up to theceiling of the car when not in use, and

which will not be difficult to open owinglto the pressure of the grainin the car; and it consists, essentially, of a door comprising.

three principal parts-an. upper hinged section, a body, and an auxiliarydoor set in and connected by hinges to the body, said hinges back orinside of my door. Fig. 3 is'a sec tional elevation of the door on theline a; as, Fig. 1. Fig. 4 is a sectional elevation of the door on theline 00 00, Fig. 1, and showing the door hanging to the roof of the car.Fig. 5 is a section through the door on the line y y,

In the drawings like letters of reference indicate corresponding partsin each figure.

A A are the jambs on each side of the door.

. B is the upper section of the door, which is provided withstrengthening-battens b b. O is the body or main section of the door,which extends about half the distance from the floor to the top of theopening and is connected to the upper section B by means of hinges b b,which are preferably made long to act as strengtheners for the uppersection B. t p

c c c are strengthening-battens extending from top to bottom of thebody. This body or main section and the upper section are Fig. 2 is anelevation of the.

p f rom side displacementwh'en in A I .p s'itio'n by the guide-stripseta, secured to theinside ofthe jambs'A'A. v g Y ,7 In the lowerportionjot thebody'of .t 1e door is'a rectangular opening 0 which jextends almost across thesaid-;body ormain'section of the door. The upperand lower edges of this opening are formed with a bevel of ap-f.proximately forty-fivedegrees and sloping in J an-upward and outwarddirection. x In this.

opening is a secondary or auxiliary doorID,

which is hinged to the body by means heroin 1 Y after described. Theupper andlower edges p of this door are beveled similarlytotheupper andlower edges of the opening 0 the lower beveled edges'of the door andopening being supplied with wear-plates E and E, re-

spectively, to prevent the wearing of said edgesfdue to their rubbingtogether when the auxiliary doorD is opened and closed. {The auxiliarydoor D is also provided with strengthening-battens d' don its inside.

The auxiliary door D is connected to the I 7 body (3' by'asuitablehinge, and preferablya crank-hinge,made as follows: Bearings 01dd are provided and secured to the auxiliary door D, one beingpreferably near each of its sides and one at the center thereof. A rod Fis provided and bent to form a series of U-' shaped cranks ff f, thelower portions of these cranks being journaled in the bearings d d (1respectively. Thestraight'portions of the rod are journaled in bearingsd d d (1 secured to the body portion of the door, these bearings being alittle above the upper edge of the door D. (Jranksf f are formed at theends of the rod F, and when the door D is closed these cranks engagewith stops G G, secured to the j-ambs. H is a substantially V-shapedlever which is welded'or otherwise joined at its upper ends to the rodF, the lower end being bent-'to'form aloop h. The loop h maybe securedto the bottom part of the body by any suitable mean'sto se-v cure thedoor D in the closed position. The means which I employ to accomplishthis'end is to provide an eyeboltLv'vhich passes through through thiseye, thus securely fastening the door in theclosed position.

J J are loops or eyes secured to the inside of the body portion of thedoor. Rods K K are provided,theirlower ends passing through the eyes J Jand terminating in eyes is k, which are sufficiently large to preventthe ends of said rods from slipping through the eyes J. The upper endsof the. rods K are pivotally held by pins L, passing through the lugs L,formed on the plates L which are firmly secured to the upper part of thejambs A A.

7.3 are two hooked portions formed near the top of the rods K K.

Hooks or catches M M are pivotally secured to the jambs in order to holdthe hinged upper section 0 in place.

By reference to Fig. it will be seen that the lower part b of the bodyof the door is thicker than the upper 'part and the center batten issprung slightly, leavinga space between said batten and the door D. Thisis to prevent the grain getting in between the door and the batten andkeeping the door from closing tight.

Having thus described the construction of my door, I will proceed toexplain its use and its advantages.

\Vhen the door is in use and in the closed position, as shown in Figs.1, 2, and 3, the body portion rests against the jambs A A and betweenthe guides or strips a a the upper hinged section B is turned up andheld in place bythe hooks or catches M M, and the auxiliary door D isclosed and looked, as above described, the cranks f f and the hooks M M,together with the pressure of the grain, holding the entire door tightlyin position. In order to unload the car, the lever H is unlocked andraised, turning the rod F in its bearings. This motion draws the door Dupward and outward in the direction of the bevel until it is entirelyfree from the body portion, and the grain rushes out of the opening 3,thus relieving the pressure on the inside of the door. It will benoticed that owing to its beveled edges the auxiliary door is notretarded but rather assisted in its opening by the pressure of thegrain. This is an important point of my invention and has not beenaccomplished previously. The pressure having been released, the catchesM M are unhooked and the upper section C is turned down against the bodyB. The whole door is now slipped up the rods K K on the hooks Z0 and isthen swung up to the roof of the car and held in such raised position bymeans of the hook N, as shown in Fig. 4. The rest of the grain may nowbe unloaded.

The reason for having the door formed with the hinged upper section B isto enable the door to hold the full load of grain and still not extendmore than half-way across the car when it is in the raised position.

It may here be observed that the battens on the upper section and thebattens on the body of the door are so arranged that they will notinterfere when the said uppersection is turned over onto the body to behung up.

I am aware that grain-doors have been constructed with lower auxiliarydoors; but they have been difficult to open or have been detachable fromthe body of the door, and consequently frequently lost. It will be seenthat my invention overcomes these difficulties.

What I claim as my invention is 1. In a door of the class described, thecombination with the body thereof, of an auxiliary door set in anopening in said door-body, the upper and lower edges of said opening andsaid auxiliary door being beveled with an upward and outward slant, andmeans for locking and unlocking said auxiliary door, as and for thepurpose specified.

2. In a door of the class described, the combination with the bodythereof, of an auxiliary door set in an opening in said door-body, theupper and lower edges of said opening and said auxiliary doorbeingbeveled with an upward and outward slant, and a crankhingeconnection between said auxiliary door and said door-body and means forlocking and unlocking said auxiliary door, substantially as and for thepurpose specified.

3. In a door of the class described, the combination with the bodythereof, of an auxiliary door set in an opening in said door-body, theupper and lower edges of said opening and said auxiliary door beingbeveled with an upward and outward slant, and a crank hinge formed of arod bent to forin cranks and straight portions, said straight portionsbeing journaled in bearings attached to the door-body, and the cranksbeing journaled in bearings attached to the auxiliary door, and meansfor locking said door as and for the purpose specified.

4. In a door of the class described the combination with the door-jambs,the body, the auxiliary door and the bent rod for the crankhinge, ofcranks formed at the extremities of said bent rods, and stops secured tothe jambs of the door, said cranks being adapted to engage with saidstops as and for the purpose specified.
